Incremental Hosting

Prerequisites

• An OBS bucket to be hosted has been authorized. For details, see Bucket Authorization.
• If you need to transcode media files or use a workflow to process these files in the OBS bucket, you can create a transcoding template by referring to Transcoding Settings or create a workflow by referring to Workflow Settings.

Notes

• If incremental hosting is enabled, VOD only hosts new files in the bucket. Files already in the bucket will not be hosted.
• If a file is added to an authorized OBS bucket, you can use SMN to get notifications about this. Enabling this function will incur fees. For details, see SMN Pricing Details.
• Incremental hosting is not available for IAM users. You are advised to use a Huawei Cloud account for incremental hosting.

   Table 1 Incremental hosting parameters

   Parameter	Description
   Name	Configuration name of incremental hosting. Enter a maximum of 128 characters, including letters, underscores (_), and digits.
   Input Bucket	Bucket to be hosted
   File Type	Types of files to be hosted in the OBS bucket
   Template/Workflow	Select a transcoding template or workflow to process hosted media files.
   Storage Location	The following storage locations are supported: VOD: Output files are stored in VOD. OBS bucket: Output files are stored in an OBS bucket. OBS bucket (same as input files): Output files are stored in an OBS bucket (which cannot be the input bucket) and their storage directory is named the same as the storage directory of input files.

   If Storage Location is set to OBS bucket (same as input files), the storage path of the generated file varies depending on the service type.

   Suppose the input file storage path is vod1/input/video.mp4 and the output bucket is vod2. Table 2 describes the paths for storing outputs.

   Table 2 Storage path parameters

   Media Processing	Output Path
   Transcoding	HLS format One-in one-out template: vod2/input/index.m3u8 One-in multiple-out template: vod2/input/video_0.m3u8, vod2/input/video_1.m3u8, ... MP4 format One-in one-out template: vod2/input/video.mp4 One-in multiple-out template: vod2/input/video_0.mp4, vod2/input/video_1.mp4, ... DASH format: vod2/input/video.mpd

   Thumbnailing	vod2/input/video_Cover0.jpg
